Some web developers call MapPath on form input to find out where to get/save
files... allowing Parent Paths could mean an unauthorized file viewage or
overwrite.

Writing a new IIS policy :

summary: Parent Paths allows you to use '..' in calls to MapPath and the
like. By default this option is enabled and should be disabled. To disable
this option go to the root of the Web site in question, right click select
Properties | Home Directory | Configuration | App Options and uncheck Enable
Parent Paths.

my question: What security hole/hack does this create if left enabled?.
